HAY-LOADER.

To all whom it may concern Be it known that I, LYMAN MELVIN JoNns, a subject of the King of Great Britain, residing in the city of Toronto, county of York, Province of Ontario, Canada, have invented certain new and usefullmprovements in Hay-Loaders, of which ing is a specification.

This invention relates to hay loaders of the type in which a plurality of kicker or bumper bars are adapted to operate alternately to raise the hay up the inclined elevator chute, and my object is to improve the construction of a loader of this type to facilitate the raising Of the hay from the ground under various crop conditions and to satisfactorily prevent the entanglement of hay in the teeth of the kicker bars nearest to the ground.

I attain my object by means of the constructions hereinafter described and illus trated in the accompanying drawings in which 7 Figure 1 is a side elevation of a loader constructed in accordance with my invention; s

Fig. 2 a front elevation of the same;

Fig. 3 a detail of the adjusting means for the swivel wheels;

Fig. 4 a perspective detail of the guard for the lower kicker bar teeth;

Fig. 5 a detail of one of the upper crank shaft bearings, and I Fig. 6 is a perspective detail of one of the pairs of kicker teeth at the lower ends of the kicker bars. t

In the drawings like numeralsof reference indicate corresponding parts in the different figures.

The elevator chute 1 is of ordinary construction, being provided with a bottom 33, and sides at, the latter tapering inwardly from the bottom toward the top. The chute is supported by aframe work 2-, which in turn is supported by the main ground wheels 3.

The. elevating mechanism comprises a plurality of kicker or bumper bars 4: provided with rake teeth 5. tuated by means of two crank shafts 6, suitably journaled on the chute, provided with cranks 7 extending alternately in pposite directions and journaled on the kicker bars. The kicker bars th'us form two series which Application filed October a, 1916. Serial No. 123,540.

the follOw-- These bars are ac- Specification of Letters Extent. 1 Patented Apr. 16; 1918 alternately operate on the hay passing up I .the chute, as the crank shaft is rotated.

The crankshafts are also provided with end cranks 8 connected by a pitman 9 so that the crank shafts may be simultaneously actuated. I deem it preferable to reduce the spacing between the cranks of the upper crank shaft as compared with the cranks of the lower crank shaft to suit the kicker bars to the taper of the chute. I find superior. results may thus be Obtained.

crossed, holds the parts of the chain from interfering, with one another.

The lowericrank shaft 6is journaled in fixed bearings, but the upper crank. shaft is carried in bearings 14 slidable to and from These idlers support the lower'part of the sprocket chains passing from the wheels 12, and the chains being the bottom of the chute insuit'able guides 15. With this arrangement the kicker bars may lift away from the bottom of the. chute to prevent choking when the machine is working on a very heavy crop. The contraction of the sides of the chute bunches the hay so thatit is more readily acted on by th'eteeth .ofthe kicker bars but this has 1 some tendency to choke the loader adjacentthe top which tendency is overcome by the floating of the upper crank shaft as described. I

A hinged extension 16 is provided at the extending beyond the len'd'of the main porbe positioned to. properly discharge the'hay upper end of the chute. The kicker bars by means of a bar 17 pivotally connected with the under side of the-extension provided with notches 18 at its lower end where'- by it may be engaged with asuitable .part 19 of the frame in any one of-several posi tions.

The lower end of each'kickerbar is provided with a short transverse bar 20 for the connectionj of two springteeth'21. These teeth are'preferably integral with-one an= other (see Fig. 6) each formed with a coil 22 surrounding the transverse bar, the ends of the coils being inserted in or otherwise proximatelytriangular in form and are se-T cured between the kicker bars and the transverse bars, being in width substantially equal to the length of the transverse bars.

To permit of the free action of the coils 22 an opening is cut on each side of each guard plate into which the upper parts of the coils may project. These guardplates effectively prevent hay catching in the spring coils or in the angles between. the kicker bars and the transverse bars and also'brace the transverse bars to the kicker bars.

I have found that different crop conditions require that the lower ends of the kicker bars and of the chute shall beset'at different distances from the ground, and to provide for this the following constructions have been devised and combined.

The lower end of the bottom of the chute is formed by a hinged board 24. This hinged board may be swung down to the position shown in full lines in Figs. 1 and 2, or may be swung up to the position shown in dotted lines in Fig. 1. A coil spring 25 is provided at each side connected with the frame in such a position that it tends to yieldingly hold the hinged board 24 in either position. With a very heavy crop the board will probably require to be swung up to the dotted position. For light and normal crops it will require to be set in the position shown in full lines. Owing to its being spring held, it will, however, yield to provide room for the raising of any special large accumulation of hay which the loader may meet with.

The distance of the lowerv ends of the kicker bars from the ground is regulated by providing the swivel wheels 26 with means of adjustment onthe frame. Each swivel wheel is journaled on the lower end of an axle 27, which is bent upwardly to form a journal 28 journaled in a bracket 29.

This bracket is slotted to slide on bolts 30.

1 secured to the frame and extending through jaws 32 formed on or secured to the bracket '29. Between these j aws'a nut 33 is threaded on the screw. It is evident that by rotating the nut,.the bracket 29 may be raised or lowered as desired. By suitably adjustingthe position ofthe' swivel wheels relative to the frame, theposition of the lower ends of the @oples or this patent may be obtained for five cents each, by addressing the Washington, D. (3.

chute and the kicker bars may be adjusted as desired, and further adjustment to difierent crop conditions may be provided by suitably positioning the hinged board2 l.

What I- claim as my invention is 1. In a hay loader, the combination of an elevator chute provided with a bottom and sides; a transverse throat board hinged at the lower end of the bottom so that it may be swung up and down; spring means tending to maintain said board in normal position; a'plurality of crank operated kicker bars adapted to raise hay or the like up said chute; a pair of swivel wheels for the lower end of the frame; and means for vertically I adjusting the swivel wheels.

2. In a hay loader, the combination of an elevator chute provided with a bottom and sides and tapering inwardly from the bot tom toward the top; a transverse throat board hinged at the lower end of the bot tom so that it may be swung up and down; spring means tending to maintain said board in normal position; rotary crank shafts journaled transversely of the chute provided with cranks extending alternately in opposite directions; a plurality of kicker bars journaled on said cranks, the upper crank shaft being arranged to float; a pair of swivel wheels for the lower end of the frame; and means for vertically-adjusting the swivel wheels.

3. In a hay loader, a kicker bar having a said transverse bar and tapered at its upper I end, and cut out at each side to give play to the spring coils of the kicker teeth, and to brace. the transverse bar.

4. In a hay loader, a kicker bar having a short transverse bar secured to its lower end; integral kicker teeth secured to the transverse bar, one at each side of the kicker bar, and each formed with a coil surrounding the bar, the coils being integrally connected by a loop; and a guard plate secured to the underside of the kicker bar and substantially covering said transverse bar and tapered at its upper end, and cut out at each side to give playto the spring coils of the kicker teeth, and to brace the transverse bar.
